v Specification of Letters Patent.

Application led November 29, 1915. Serial No. 63,942.

To all whom it may concern:

Be it known that I, GEORGE G. POWERS a citizen of the United States,residing at Chicago, in the county of Cook yand State of Illinois, haveinvented certain new and useful Improvements in Bed-Springs, of whichthe following is a specification.

My invention pertains to features of novelty and advantage inbed-springs or wiremattresses, and the like, and concerns moreparticularly the manner of supporting the spring Or mattress on thebed-stead fram-e or side-rails. y

One object of the invention is to so construct and mount the bed-springas to balance or oppose the strains imposed upon the same as much' aspossible, to `permit the structure to be made of light gage materialwithout loss of strength, and also to improve the functionalcharacteristics of the appliance. Y l

A further purpose of the invention is to produce a'structure of thischaracter, wherein the bed-spring will tend to maintain its horizontaldisposition 'even though unevenly loaded, as by occupants of greatlydiering weights.

In my `prior patent, No. 1,154,986, bed spring, granted September 28,1915, there is shown a construction of this general character, whereinthe mattress-frame and the fabric mounted thereon are supported from ahanger-construction resting on the bedframe by meansv of-coilv tensionsprings, kthe fabric and these springs both being -located above theside-rails, of the mattress-frame, the hanger-constructionbeingpositioned be-v tween the fabric and such side-rails. In thestructure lof the patent, it will-be noted that all of the strain`imposed onthe mattressframe side-bars is at one side, that is, abovethe side-bars, which requires substantial end supportsor bracketsandresults'in an unnecessary cumulative effect Of the strain produced inthe struct-ure.

As has been indicated above, one of the iolojects of the presentinvention is to-s`o modify the kdeviceof the patent.v as to,gatleast inpart, neutralize or opposesuch strains, for the purpose indicated.

In the preferred embodiment of the invention this is brought about byhaving .the fabric above the mattress-frame side-bars and thehanger-construction and the supporting springs below such side-bars, sothat -modied construction;

Aparts shownin Fig. 7

there will'be amore even or balanced distribution ofthe strainsproduced, which per-V mits tlie 4employment "of a lighter weightstructure without sacrifice of strength.

In Order that those skilled in this art may have a full understanding ofthe invention', I have illustrated several embodiments of the sameV inthe accompanying drawings which form a part of this specification andyto which reference should be made in connection with the followingdetailed description. In the various views of these drawratentea oct.1e, 1917.

Referring to the form of devicev shown in Figs. 1 to 6 inclusive, vitwill be noticed/that a portion of .the bedstead-frame is illustrated, le., two corner-posts 20 and 21 connected together bythe usual side-rail22.

Inasmuch as both sides of the mattressconstruction are alike, ,it isonly necessary` t0 illustrate andl describe one side portion of thesame.The mattress-frame comprises two side-bars or rods 23, each of which ateach end is equipped with a standard or bracket '24,. composed of ametal strap bent to provide apart .25 extended both aboveand below theside-bar, as shown, and equipped with a .socket 26 receiving the end ofsuch side-bar. At its top this member 24 is bent down Aas iiidicated,toJ provide an ear 2on top of' the "sidebalr, 'the bottom-end of member24 being bent inwardly at28, such portion having riveted thereto asupplementalA bracket 29 projecting under the bar 23, the, two parts27and.29,being secured .to theV side-biar'by means of'rivets 3Q. The parts27 and 29 where they Contactv withithe top' and bottom faces4respectively of Vthe side7 bar' are urvedgas shown: in `Fig. 4,` toxsecure an "eec'tive Contact betweenthe elements. Each l end of themattress-frame at 'its top is equipped'with a transverse langlglebar 31,to which a Iwire-"fabricV 32 o f any suitable constructionis y'connectedby means of the, usual helical springs 33,Y As is customary in:structures of this general character, "the sidefinargins of the'mattress'are provided with flat'metal straps or ribbons 34 Aconnectedtatjftlieir ends'byj means" of helical V*springs ,35` with` the cross#bar's vf31, these parts 34, beingv associated A the adjacent portions ofthe wire-fabric by] -suitable links or other.connectingfeleinents.
